Need help with Algebra 2!!

[kitkat17]

Diana received 65 points on a project for school. She can make changes and receive three-tenths of the missing points back. She can make as many corrections as she wants. Create the formula for the sum of this geometric series and explain your steps in solving for the maximum grade Diana can receive. Identify this as converging or diverging.

I don't know how to solve this. Can you PLEASE help!!!???

Hi kitkat:

Do you know what a geometric sequence is? Do you understand the definition of "series"?

Please explain what you've thought about or tried so far.

But first, check out the forum guidelines; here's a link to the summary page. (You'll find links to the complete rules and guidelines near the bottom.)

Cheers

The first thing you will need to know is "How many missing points were there?" Are we to assume that there were a total of 100 possible points so that if she got 65 there were 35 "missing" points?
